This archive includes all raw mass balance and GPS (global positioning system) data from survey poles on McCall Glacier, arctic Alaska, from 2003 to 2014 and all reductions of it through 2022. McCall Glacier has been studied since 1957 and the research program there is one of the most comprehensive of any glacier worldwide. This data archive is organized by field campaign, twice annually, with all known raw and reduced data placed within the campaign's folder along with a reduced spreadsheet and notes for each campaign. A single reduced master spreadsheet captures the reduced data from all campaigns. Both the mass balance and velocity data time-series were analyzed in detail in this master spreadsheet and all corrections annotated within a 460 page PDF, which describes the data collection methods, the data reduction methods, and the data archive itself. Corrections to the raw data discovered in the time-series analysis, as described within the PDF, were placed within a corrections spreadsheet designed to be added cell by cell to the master spreadsheet. The PDF also includes various plots for each survey pole's mass balance and motion to facilitate quick visualization of the data. Scans of fieldbooks and online blogs related to individual campaigns are captured here as well to provide context for the measurements.
